When the fruit vendor came to Vrndavana, Krishna took some grains and immediately went as if to barter with her. On the way he dropped most of the grain. Still, the fruit vendor filled Krishna's hands with fruits and immediately her basket became filled with jewels and gold."From this incident one should learn that for anything offered to Krishna with love and affection, Krishna can reciprocate many millions of times over, both materially and spiritually." -Excerpt from Srila Prabhupada Purport, Srimad Bhagavatam 10.11.11
